To all whont it may concern:

Be it known that 1, CHARLES LYNCH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dumping-Vagons, of whichthe following is a specification.

My invention relates to dumpingwagons, and more particularly to the kindthat has removable boxes for conveying sand, stones, coal, or the likein the transportation of which the wagon is used.

My improved mechanism comprises an easily-actuated means for causing thesand or other material to be dumped from the box, and also includesmeans to permit moving the actuating mechanism out of the way, so that aderrick or similar hoisting device can remove an empty box from thewagonframe and replace it with a loaded one.

In the accomp anying drawings 1 have illustrated the preferredembodiment of my invention, and on said drawings Figure 1 is a sideelevation of a wagon equipped with a dumping mechanism embodying myinvention. fig. 2 is a plan view of the device shown in b ig. 1. 1* ig.3 is a rear elevation of the wagon. Fig. 4 is a similar elevationshowing the two parts of the box in position to dump their contents, andfig. 5 is a detail view of the pivotal arrangement for the supportingmeans for the box-lif ting mechanism.

The wagon equipped with my improved dumping mechanism is of the usualtype, comprising front wheels 10, rear wheels 11, and the other ordinaryparts of the running gear of a wagon, including front and back bolsters13 and 14. The main frame of the wagon consists of longitudinal beams15, end beams 16, intermediate transverse beams 17, and adjacenttie-rods 18. T o the outer end of each of the bolsters 13 and 14 issecured a stake-pocket 19, the same being riveted or bolted to thebolsters. At the upper ends of members 20, fitted in the pockets 19, areattached inclined arms 21, united at their upper ends by transversemembers 22. These inclined members and their horizontal connectingmembers are preferably made of sections of pipe and elbows, the centerportions of the horizontal members 22 being supplied with Ts 23. Runningparallel with each member 22 is a similar, but shorter, pipesection 24,with a T 25 at its'central part, in alinement with T 23, the ends ofmembers 24 being supported by the inclined pipe-sections 26, suitablysecured to the longitudinal members of the wagon-frame. Inserted in theadjacent ends of the Ts 23 and 25 are plugs 27, between the heads ofwhich is held casting 28, loosely mounted upon and rotating on bolt 29,held in place by nut 30, the bolt passing through the Ts, the plugs, andpivoted member 28. Extending upwardly from each member 28 is apipesection 31, at the upper end of which is a bearing 32, within whichrotates the longitudinal shaft 33. Extending downwardly from each member28 is a pipe-section 34, provided with a perforated projection 35, andon the frame of the wagon is a member 36, with upstanding perforatedears, through which pin 37 passes, acting in conjunction with projectionto hold the support in vertical position. On the forward side of frontsupport 31 is rotatively mounted pinion 38, provided withoperating-handle 39, the pinion meshing with gear 40, fixed to a shortshaft passing through bearing 41 at the upper portion of supportingmember 31. Pinion 42 on the inner end of this shaft meshes with gear 43,keyed to the main shaft 33. It will be evident from this constructionthat by turning handle 39 shaft 33 is rotated by means of the gearsdescribed above. On the shaft 33 are four chains 44, which are securedto the flanges of members 45, fixed to the shaft. This constructioninvolves, therefore, a forward and rear pivoted supporting member, thetwo being joined together by the shaft rotating in bearings at theirupper ends. The forward support is provided with a handle and gears foractuating the shaft, which has attached to it a plurality ofhoistingchains.

The dumping-box of the wagon, which rests upon the wagon-frame,comprises two receptacles 46, with their open mouths 46 facing eachother, the two receptacles being pivoted to each other at the top byhinges 47. At the upper outer sides of the box I provide ears or lugs48, with which the chains 44 may be engaged by means of hooks at theirends. The two portions of the box are held together and prevented fromopening, when the box is elevated by means of chains the staple 49.

44, by staple 49 on one part of the box and arm 50, pivoted to the otherhalf of the box at the point 51, pin 52, chained to the end of the box,being adapted for insertion in staple 49 to hold arm 50 with its loop atthe end over A fastening means of this type is provided at each end ofthe box.

The operation of the device is as follows: With the two halves of thebox fastened together by the locking means at each end de scribed aboveand with the chains 44 attached to the ears 48 the vehicle is driven tothe point where its contents are to be dis charged. The operator unlocksthe two parts of the box, removing pins 52 and separating arms 50 andstaples 49, and by turning the handle 39 elevates the same, the boxopening up and discharging a portion, if not all, of its contents due tothe relative position of the hinges and the ears 48. By this operationchains 44, attached to the opposite sides of the box, are wound up onshaft 33 in reverse directions, and as the box continues to be elevatedthe chains draw in sufficiently on the attached lugs 48 to open the boxto its fullest extent, thereby discharging the total contents. The boxor receptacle is then lowered by turnin the crank 39 in the oppositedirection. T e. two halves of the box are locked together and thevehicle driven to the spot where it is to receive a new load. At thispoint the chains 44 are unhooked from cars 48, pins 37 withdrawn, andthe pivoted supports 31, with their connecting shaft 33, turned on theirpivots, so as to be out of the way of the box, as shown in Fig. 3, topermit the latter to be raised by a derrick or similar hoisting device,the ends of whose chains are secured to the ears 48.

It will be apparent from this construction and description that theboxes can be quickly and easily removed from the wagon and that whenthey are on the wagon-frame they can be readily dumped by turning thecrank or handle 39.
